Detailed Description

The system is designed for VLF (0.1 Hz) withstand testing of cross-linked polyethylene (XLPE) insulated cables.

  • VLF testing of cables with polymeric insulation (incl. XLPE cables).
  • Hipot testing of solid dielectrics with DC voltage of positive or negative polarity.
  • Cable faults conditioning by initial insulation burning.
  • Vacuum bottle test.
  • Cable sheath testing and fault pinpointing.


VERSATILITY
Apart from very low frequency (VLF) and DC withstand testing, VLF-60 system also performs cable fault conditioning by initial burning faulty insulation, tests cable sheath and pinpoints its faults.


MANUAL AND AUTOMATIC OPERATING MODES
The system allows to carry out tests in both automatic and manual control modes.
In the manual mode the operator enters all test parameters, which makes VLF‑60 suitable for testing a wide range of electrical equipment according to various standards and regulations.
In the automatic mode minimal test settings entries are required: the operator only selects a test object type and voltage rating and the system automatically sets all the necessary test parameters according to IEEE 400.2-2013.


TESTING HIGH-CAPACITANCE OBJECTS
At the start of every test, VLF-60 measures the resistance and capacitance of an object under test. Based on the obtained results, the system evaluates its power output capability. If the system is not able to output the voltage of a required magnitude and frequency for a given load, it will automatically reduce the output frequency. Thanks to such output frequency optimisations, the VLF-60 can be used effectively for testing objects with capacitance up to 10 µF.


10,000 TEST REPORTS STORAGE
Non-volatile memory of the system capable of storing up to 10,000 test reports.

It is possible to search and view test reports right from the display of the system.

Test reports may be exported from the system to a USB memory stick in CSV or PDF format without using a PC.


TOUCH CONTROL
The main user interface component is a touch-sensitive colour TFT display, which is used for navigating menus and entering data. During a test, an output voltage wave is visualised on the display in real time.


PORTABILITY AND SMALL WEIGHT
VLF-60 system is fitted with carrying handles and weighs only 64 kg, which enables operational comfort both in the lab and in the field conditions.


SAFETY

  • Dual discharge device (internal automatic protection).
  • Visual indication of high voltage presence on an object under active test.
  • Visual indication of residual or stray voltage presence on an object after conclusion of a test.
  • Sound alarm when high voltage is switched on.
  • Emergency stop button.
  • Operator keylock switch.
  • Protective earthing.

VLF-60 Cable Insulation Tester

http://www.kep.ua/en/device/139/vlf-60-hipot-tester/ VLF-60 Cable Insulation Tester made by KEP is a very low frequency high potential tester that ensures efficient testing and fault location on medium voltage cables. Very low frequency (VLF) testing involves applying frequency in the range of 0.01 to 0.1 Hz to the cable under test, which is non-destructive to insulation of proper quality, but is enough to detect cable faults.
